Would 2 adults in their 40's have a good time at DC? We are leaving the kids home on this trip & mostly planning on relaxing at the resort as DH doesn't like theme parks but thought this might be a fun day out. We are very active, enjoy snorkeling, and like to have a few cocktails. Just trying to figure out if the cost of admission would be worth it and if there is enough there to keep us busy for the day. Would not do the dolphin swim as we've already done that a couple times in other locations.
